These graphs show mixer Third Order Intercept (TOI) vs. frequency referenced to the input of the mixer (that is, referenced
to the RF port in the case off a down-converter, or the IF port in the case of an up-converter), with both low-side LO excita-
tion (LO frequency below the RF frequency) and high side excitation (LO frequency above the RF frequency). Operation
both as a down-converter and an up-converter is shown, with LO powers of 14, 17, and 20dBm. In all cases, the IF fre-
quency is 150MHz. The RF power used in measuring third order intercept is +4dBm. Note that third order products closely
follow the expected 3:1 slope.
